[0006] The stone throwing device described in the present application hoists the stone to a predetermined position by means of the main hoisting assembly and the auxiliary hoisting assembly, and then separates the main hoisting assembly from the stone by means of the auxiliary hoisting assembly, thereby achieving the purpose of separating the main hoisting assembly from the stone. The entire process of separating the main hoisting assembly from the stone does not require human intervention, thus avoiding safety risks to personnel during the lifting process.

[0007] Preferably, the first sub-head, the second sub-head and the female head are connected by a pin, the first hook is hung with the bottom chain, the second hook is hung with the bottom chain, the third hook is hung with the fourth chain, and along the length direction of the bottom chain, the first hook is located between the female head and the second hook.

At this time, the first sub-chain, the second sub-chain, the part of the bottom chain located between the second hook and the female head and the part of the fourth chain located between the third hook and the second sub-head form a ring. The structure is then lifted, the first hoist and the second hoist are lifted, so that the first chain, the second chain, the third chain, the fourth chain and the bottom chain lift the stone together, at this time, the first hoist rope is in a relaxed state, and the part of the fourth chain between the third hook and the second hoist is also in a relaxed state; after the stone is lifted to the target position, the first hoist is lowered for a distance, so that the first chain, the second chain and the third chain are all in a relaxed state; then the second hoist is lifted, so that the first hoist rope drives the latch to separate from the first sub-head, the second sub-head and the mother head, so that the bottom chain is in a relaxed state, and the part of the fourth chain between the third hook and the second sub-head is also in a relaxed state; the first hoist and the second hoist are lifted, so that the first sub-head, the second sub-head and the mother head are separated; the first hoist and the second hoist are lifted continuously, and the first hoist and the second hoist are separated from the stone. Thus, the purpose of separating the main hoist assembly from the stone is achieved, and the whole process of separating the main hoist assembly from the stone does not require manual participation, avoiding the safety risks of personnel in the lifting process.

[0013] When lifting stones, the first lifting rope will have a certain torsional force during use, which will bring a small risk of causing the latch to rotate. In this case, the first lifting rope is configured to include a first flexible rope, a first chain segment and a second flexible rope connected in sequence, thereby releasing the torsional force on the first flexible rope; At the same time, since the length of the second flexible rope is ≥0.5m, it is avoided that when the pin is pulled out of the mother head, the chain links of the first chain segment interfere with the first sub-head, the second sub-head, the mother head or the chain links of the bottom chain or the chain links of the fourth chain, resulting in the main lifting assembly or the auxiliary lifting assembly being unable to detach from the stone.

[0014] Preferably, there are at least two first chains.

A section of the fourth chain close to the second sub-head is formed into an arc shape around the stone from the other side of the stone and tightened, and the third hook is connected to the fourth chain, so that the second chain, the third chain and the fourth chain hold the stone from the other side of the stone. At this time, the first sub-chain, the second sub-chain, the part of the bottom chain located between the second hook and the female head and the part of the fourth chain located between the third hook and the second sub-head form a ring structure; S5. Lift the first lifting device and the second lifting device so that the first chain, the second chain, the third chain, the fourth chain and the bottom chain jointly lift the stone, at which time, the first lifting rope is in a relaxed state, and the portion of the fourth chain between the third hook and the second lifting device is also in a relaxed state; S6.

The entire process of separating the main lifting assembly from the stone does not require human intervention, thus avoiding safety risks to personnel during the lifting process.

[0018] Preferably, the end of the latch connected to the first lifting rope is directed toward the stone. During the lifting process, since the fourth chain and the bottom chain are both close to the stone and in a tensioned state, the latch is connected to the first lifting rope with the end directed toward the stone to ensure that the latch does not separate from the female head during the lifting process. After the stone is lifted to the target position, the second lifting device is lifted so that the first lifting rope drives the latch to rotate vertically, and then the second lifting device continues to be lifted, thereby driving the latch to smoothly separate from the first sub-head, the second sub-head and the female head.

[0036] At the same time, the main purpose of using the first lifting rope 21 instead of the chain is to avoid interference between the chain links and the first sub-head 63, the second sub-head 64, the female head 62 or the chain links of the bottom chain 15 or the chain links of the fourth chain 22 when the pin 65 is pulled out of the female head 62, resulting in the main lifting component 1 or the auxiliary lifting component 2 being unable to detach from the stone.

[0037] The stone throwing device described in the present application hoists the stone to a predetermined position through the main hoisting component 1 and the auxiliary hoisting component 2, and then separates the main hoisting component 1 from the stone by using the auxiliary hoisting component 2, thereby achieving the purpose of separating the main hoisting component 1 from the stone. The whole process of separating the main hoisting component 1 from the stone does not require human intervention, thus avoiding the safety risks to personnel during the lifting process.

[0038] In a preferred manner, the first sub-head 63, the second sub-head 64 and the female head 62 are connected by a pin 65, the first hook 31 is hung with the bottom chain 15, the second hook 32 is hung with the bottom chain 15, the third hook 33 is hung with the fourth chain 22, and along the length direction of the bottom chain 15, the first hook 31 is located between the female head 62 and the second hook 32.

[0041] The stone throwing device described in the present application is used for stone throwing. During construction, the first chain 11, the second chain 13 and the third chain 14 are arranged along the circumference of the stone, and the first sub-head 63, the second sub-head 64 and the female head 62 are matched, and the latch 65 passes through the first sub-head 63, the second sub-head 64 and the female head 62; then, a section of the bottom chain 15 close to the female head 62 is formed into an arc shape around the stone 10 from the bottom of one side of the stone 10 and tightened, and the first hook 31 is hung on the bottom chain 15, and the second hook 32 is hung on the bottom chain 15. Then, a section of the fourth chain 22 close to the second sub-head 64 is formed into an arc shape around the stone 10 from the other side of the stone 10 and tightened, and the third hook 33 is hung with the fourth chain 22, so that the second chain 13, the third chain 14 and the fourth chain 22 are held from the other side of the stone 10. At this time, the first sub-chain 16, the second sub-chain 17, the bottom chain 15 between the second hook 32 and the female head 62 and the fourth chain 22 between the third hook 33 and the second sub-head 64 The first hoist 4 and the second hoist 5 are partially enclosed into a ring structure, and then the first hoist 4 and the second hoist 5 are lifted, so that the first chain 11, the second chain 13, the third chain 14, the fourth chain 22 and the bottom chain 15 jointly lift the stone 10. At this time, the first hoist rope 21 is in a relaxed state, and the portion of the fourth chain 22 between the third hook 33 and the second hoist 5 is also in a relaxed state; after the stone 10 is lifted to the target position, the first hoist 4 is further lowered for a distance, so that the first chain 11, the second chain 13 and the third chain 14 are all in a relaxed state; then The second lifting device 5 is lifted, so that the first lifting rope 21 drives the latch 65 to be separated from the first sub-head 63, the second sub-head 64 and the female head 62, so that the bottom chain 15 is in a relaxed state, and the portion of the fourth chain 22 between the third hook 33 and the second sub-head 64 is also in a relaxed state; the first lifting device 4 and the second lifting device 5 are lifted, so that the first sub-head 63, the second sub-head 64 and the female head 62 are separated; the first lifting device 4 and the second lifting device 5 are continued to be lifted, and the first lifting device 4 and the second lifting device 5 are separated from the stone 10.

Based on the stone throwing device for stones described in Example 1, the stone throwing method comprises the following steps: S1. Arrange the first chain 11, the second chain 13 and the third chain 14 along the circumference of the stone; S2. Match the first sub-head 63, the second sub-head 64 and the female head 62, and pass the pin 65 through the first sub-head 63, the second sub-head 64 and the female head 62; S3. A section of the bottom chain 15 close to the female head 62 is formed into an arc shape around the stone 10 from below one side of the stone 10 and tightened, and the first hook 31 and the second hook 32 are both connected to the bottom chain 15, so that the first chain 11, the second chain 13, the third chain 14 and the bottom chain 15 hold the stone 10 from one side of the stone 10; S4.

At this time, the first sub-chain 16, the second sub-chain 17, the part of the bottom chain 15 located between the second hook 32 and the female head 62 and the part of the fourth chain 22 located between the third hook 33 and the second sub-head 64 form a ring structure; S5. Lift the first sling 4 and the second sling 5, so that the first chain 11, the second chain 13, the third chain 14, the fourth chain 22 and the bottom chain 15 jointly lift the stone 10, at which time, the first lifting rope 21 is in a relaxed state, and the portion of the fourth chain 22 between the third hook 33 and the second sling 5 is also in a relaxed state; S6. After the stone 10 is hoisted to the target position, the first hoist 4 is lowered for a distance so that the first chain 11, the second chain 13 and the third chain 14 are all in a relaxed state; S7. Lift the second sling 5, so that the first lifting rope 21 drives the latch 65 to disengage from the first sub-head 63, the second sub-head 64 and the female head 62, so that the bottom chain 15 is in a relaxed state, and the fourth chain 22 is located between the third hook 33 and the second sub-head 64 is also in a relaxed state; S8. Lift the first spreader 4 and the second spreader 5 so that the first sub-head 63, the second sub-head 64 and the female head 62 are separated; S9. Continue to lift the first sling 4 and the second sling 5, and separate the riprap device from the stone 10.

[0049] The stone throwing method described in the present application comprises the following steps: the stone is lifted to a predetermined position by the main lifting component 1 and the auxiliary lifting component 2, and then the main lifting component 1 is separated from the stone by the auxiliary lifting component 2, thereby achieving the purpose of separating the main lifting component 1 from the stone. The entire process of separating the main lifting component 1 from the stone does not require human intervention, thereby avoiding safety risks to personnel during the lifting process.

[0050] In a preferred manner, the latch 65 is connected to one end of the first lifting rope 21 toward the stone 10. During the lifting process, since the fourth chain 22 and the bottom chain 15 are both close to the stone 10 and in a tensioned state, the latch 65 is connected to one end of the first lifting rope 21 toward the stone 10 to ensure that the latch 65 does not separate from the female head 62 during the lifting process. After the stone 10 is lifted to the target position, the second lifting device 5 is lifted so that the first lifting rope 21 drives the latch 65 to rotate vertically, and then the second lifting device 5 continues to be lifted, thereby driving the latch 65 to smoothly separate from the first sub-head 63, the second sub-head 64 and the female head 62.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
